- Abstract:
-
This work aims at understanding the large reduction of superconducting critical temperature Tc observed in YSr2Cu3O6+χ as compared to its YBa2Cu3O6+χ counterpart (ΔTc=-30 K). We report on a combined study of structural and electronic properties of RESr2Cu3O6+χ (RE=Y, Yb) polycrystalline samples. Neutron diffraction data and Cu NQR spectra show that, contrary to REBa2Cu3O6+χ RESr2Cu3O6+χ is locally tetragonal and no CuO chains are formed. This arises from the random occupancy of oxygen along t...
